EMERGENCY-VALVE.

To all whom it may concern:

Be it known that I, Omvnn Penn, a citizen of the United States of America, residing at littsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Emergency-Valves, of which the following is a reference being had therein to the accompanying drawings, 1

This invention relates to valves, and more particularly to that type of valve commonly styled a gate valve The primary object of my invention is to gate valve that can be used in connection with steam p es.

Another object-0f this invention is the positive and reliable means in connection with a gate valve for automatically closing the same, said means being easily adjusted to insure a positive operationof the valve.

A. further object. .of this invention is to provide a simple, durable and inexpensive valve that can be used for various purposes.

\Vith the above and other-objects in view i which will more readily appear as the inveui tion is better understood, the same consists in the novel construction, combination and arrangement of parts to .be' presently described and then specifically pointed out in In the drawings :-Figure 1 is a front elevation of the valve constructed in accordance with my invention, Fig. 2 is aside elevation of the same, Fig. 3 is avertical sectional view of the valve illustrating the electrical connections, Fig. 4 is an elevation of a portion of a modified form of valve body, Fig. 5

p The oppositeend of the gatefl is oppositely is a front elevation of a portion of a valve lever, illustrating a modification of the invention, and Fig. 6 is a side elevation of the same.

In the accompanying drawings, 1 designates a valve body provided with alining ports 2, these orts being interiorly screw threaded for pipe connections. The valve body, 1 is provided with a vertical slot 3 for a gate 1. The up r end of the slot 3 is enlarged, as at 3", and formed with oppositely disposed inclined sides 3", providing a seat for the upper enlarged end 4 of the gate 4;.

formed with disposed sides for seating in the lower part of the valve or body 1, as at 5, said gate forming a non-leakable partition 1 between the ports I ing box vided with a plate of insulation 23,

, 2. It is impossible for steam to escape into the upper enlarged end 3 of the slot 3 by reason of the enlarged end -1 of the gate being firmly inclined sides 3" of said slot, said gate seating in the lower part of the body 1, as at 5, and forming a partition between the ports The gate 4 is connected to a vertical rod 6 extending upwardly casing 7 secured to the top of thevalve body l by bolts 8 and nuts 9. Mounted in the casing 7 and encircling the rod 6 is a coil spring 10-, and extending through the rod 6 between held against the through a cylindrical two 'of the convolutions of the spring -1s a and the upper end of the casing, and by ro tating the spring, similar to a screw the tension thereof can be increased or placing a greater number of convolu-tions above the pin than below and vice versa.

The upper end of the casing 7 is provided with a transverse opening 12, and in the openin 1i, through which extends the rod 6. The upper end ofthe rod 6 is threaded, at

15, for an adjustable hand wheel 16, said wheel being employed to raise the gate 6 is' provided 85 The extreme end of-the rod with a nut 15 for preventing the adjustable hand wheel 16 from being accidentally removed.

Located upon the front side of the casing decreased by 12 is mounted a gland 13 and stuff- 7 in proximity to the upper end thereof is a bearing 17 for a fulcrumed lever 18. The fi'pper end of the lever is bifurcated. as at 19. an provided with a bearing pin 19, for a ivoted beveled latch latch extendmg through an opening for engaging, a notch C32 formedin the side of the rod 6. The front side of thevalve body 1 and the casing 7 at the confronting ends thereof, are enlarged, as at 23, and-pro- 20, said electro-magnet'il l having a soft iron core 25. This electro-magnet operates in con unct1on with another magnet 26 located upon the lever 18 and suitably insulated therefrom.

connected together 105 The electro-magnets are by a wire 27 and by wires 28 and 29 to a battery 30. A suitable switch .or push button 31 is locatedupon the wire 28, whereby the energizing of the elect-ro-magnets 24 and 26 can be readily controlled.

In lieu of the two electro-magnets 24 and 26, I can' provide the enlargement. 23 with 21 111 the casing 7 for an two electro-magnets 24 and the lever 18 with to the same by bolts 35 and nuts 36.

Operation. To open the gate 4 of the valve, the hand wheel 16 is rotatedvto raise the rod 6 and place the spring 10 thereof under tension. When the notch 22 registers with the opening 21 of the casing 7, the lever 18 is swung to place the latch 20 in engage. ment with the notch 22, sucha position, of the lever separating the soft iron cores of the electro-magnets 24 and 26. The hand wheel 16 is then rotated to a raised position upon the rod 6, referably in'en'gagement with the nut 15, 1n order to clear the upper end of the casing 7 when the gate 4 is closed. By establishing a circuit through the electromagnets 2% and 26, the soft iron core of the magnet 26 is attracted to the soft iron core 25 of the electro magnet 24, this inward movement of the lowerend of the lever 18 withdrawing the latch 20' from engagement with the notch 22,,a1lowin the spring 10 to pull the gate 4 downwardly and maintain the same in a closed position. I

While inthe drawings forming a part of this application, there is illustrated the preferred embodiments of my invention, it is to be understood that the elements therein can be varied or changed Without departing from the spirit of the invention.

Having now described my invention what I claim as new, is: v

1. A valve comprising a body, a gate movably mounted therein, a casing carried by aid body, a rodsecured to said gate and exand placing said spring tending upwardly through said casing, a

.hand wheel adjustably mounted upon the upper end of said rod and adapted to engage said casingffor elevating said rod, a coil spring located in said casing and encircling said rod for lowering said rod and gate, a lever fulcrumed uponthe side of said casing, a pivoted latch carried by the upper end of said lever and extending into said casing for engaging a notch provided therefor in said rod, an electro-magnet carried by the lower end of said lever, an electro-magnet supported by said casing for attracting the first mentioned electro-magnet for moving said lever, and means carried by said rod within said casing for-increasing the tension upon said spring, substantially as describedv 2. A valve comprising abody, a gate mov- 1 ably mounted therein, a casing canried by said body, a s ring-pressed rod movably mounted in sai casing and connecting with said gate, a hand wheel arranged at the upper end of said rod for elevating the same under tension, a lever fulcrumed u on said casing, a pivoted latch carried by said lever for engagmgsaid I rod and supporting the same in an elevated position, and a pair of electro-magnetic devices associating with each other and with said lever and adapted when energized to shift the lever whereby said latch is released causing the automatic shifting of the rod in one direction to close the gate, one of said magnetic devices carried by the casing and the other by said 'lever.

In testimony whereof I aflix my signature in the presence of two witnesses.
